A display device includes a front display area (FDA), side display areas (SDAs), and a corner display area (CDA). The SDAs and the CDA are disposed outside of the FDA. The SDAs include: a first SDA disposed at a first side of the FDA; and a second SDA disposed at a second side of the FDA. The CDA is disposed at a corner of the FDA between the first SDA and the second SDA. The CDA is connected to the first SDA and the second SDA. The FDA has a flat display surface. The first SDA, the second SDA, and the CDA respectively form a bent surface. A shape of the bent surface of the CDA is different from a shape of the bent surface of the first SDA and a shape of the bent surface of the second SDA. The CDA is stretchable and/or shrinkable.

6. The display device of claim 1, wherein the first side display area and the second side display area have a smaller stretching force and/or shrinking force than the corner display area, and have a same stretching force and/or a shrinking force as the front display area.
This invention relates to a flexible display device with multiple display areas having different mechanical properties. The device includes a front display area, a corner display area, and side display areas (first and second). The corner display area is designed to withstand higher stretching and shrinking forces compared to the side display areas, which have lower stretching and shrinking forces. The side display areas share the same stretching and shrinking force characteristics as the front display area, ensuring uniform deformation behavior between these regions. This design allows the display to flexibly adapt to different shapes while maintaining structural integrity, particularly in the corner region, which is more susceptible to stress. The varying force requirements across the display areas enable the device to bend or stretch without damage, improving durability and performance in flexible display applications. The invention addresses the challenge of maintaining display functionality and longevity in devices subjected to repeated mechanical stress, such as foldable or rollable screens.
9. The display device of claim 8, wherein, in the bent state of the corner display area, at least a portion of the corner display area is shrunk.
A display device includes a flexible display panel with a corner display area that can transition between a flat state and a bent state. In the bent state, at least a portion of the corner display area is reduced in size, allowing the display to conform to a curved or angled surface while maintaining visual content integrity. The device may include a support structure that facilitates the bending and shrinking of the corner display area, ensuring smooth transitions and preventing damage. The shrinking mechanism may involve compressing or folding the display material in the corner region, enabling compact deployment in space-constrained applications. This design is particularly useful in wearable devices, foldable electronics, or automotive displays where space efficiency and adaptability are critical. The shrinking feature ensures that the display remains functional and visually coherent even when bent, addressing challenges related to distortion or misalignment in flexible displays. The support structure may include hinges, flexible substrates, or other mechanical elements that enable controlled bending and shrinking without compromising display performance. The invention improves upon existing flexible displays by providing a more compact and adaptable solution for corner regions, enhancing usability in dynamic environments.
